=head1 NAME

Software::License::GPL_3::or_later - Add-on for Software::License module providing "or any later" clause to GPL_3

=head1 VERSION

version 0.002

=head1 SYNOPSIS

In C:

    name             = Foo-Bar
    version          = 0.001
    author           = John Doe
    license          = GPL_3::or_later ; <<== Note this <<==
    copyright_holder = John Doe
    copyright_year   = 2015
    …

Direct usage:

    use Software::License::GPL_3::or_later;
    my $license =
        Software::License::GPL_3::or_later->new( {
            holder => 'John Doe', …
        } );

=head1 DESCRIPTION

C is a subclass of C. It overrides
license name — appends ", or any later", changes version to "3+", and notice to standard GNU
3-paragraph notice.

See documentation on C for description of methods.

=head1 PURPOSE

C/C, a popular framework/tool for building packages for CPAN, allows you to
specify software license in C file, e. g.:

    license = NAME

where I is a short license name, like C or C. When building your package,
C will add "COPYRIGHT AND LICENSE" section to the documentation, add appropriate C
file to your package, etc. C uses licenses provided by C package.
The latter is bundled with a set of popular software licenses, including GNU General Public License
(GNU GPL) versions 1, 2, and 3, denoted by names C, C, and C respectively.

L, a developer of GNU GPL, recommends do not stick to a
specific version of the GNU license, but allow "upgrading" it by using phrase "version I or any
later version". See L.

However, C package does not include any "upgradable" license. This module
partially fulfills the lack by providing license C.

=head1 CAVEATS

C hardcodes the list of "valid" licenses. In version 2.150001 of the module there
are no "upgradable" GNU licenses, so in CPAN the GPLv3+ will look as ordinal GPLv3.
